Yes they are full sized statues for promotional purposes.
No, they made an army of the F3 ones too:

I do notice a difference for when they promoted Obsidian's F:NV, because I can't remember them bringing out a bronzed army for that publicity campaign. But I guess they banked on the fact that F:NV still basked in the glory of the previous F3 promotion.
